Letters vPatent No. 106,959, dated August 30, 1870.

IMPROVEMENT IN LUBRICATORS.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom 'it may concern:

.Beit known that I, HUGH PRINGLE, of Green Point, in the county of Kings and State of New York, have invented anew and improved Lubricat-or; and I do hereby declare .the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to Y make and use the same-reference'being had -to the accompanying drawing forming 'part of' this specification, iu which draw- 1ng-' l .Figure :1 represents a vertical central section of this invention.A 4

YFigure 2 is a front Yview of the same.

V'Figure 3 is an inside view of the distributing-disk detached.`

b Figure 4 is a lsimilar view ofthe distributing-cham- Similar letters indicate corresponding parts.

This' invention relates to a lubricator, which is intended particularly for steam-chests, but which may also be use d for steam-cylinders and otherwise.

1t consists of an oil-cup, which communicates through a suitable channel with a distributing-chamber, in, which moves the distributing disk, and which communicates through a channel with the interior of a steamchest or other article to be oiled, in such 'a manner that, by imparting to the distributing-disk a rotary motion, a smallquantity oflubricating material is discharged into the delivery-channel once for every revolution of said disk. The motion of the distributing-disk is produced by a .ratchet-lever, which connects with the valve-rod, or any other moving part of the engine, in such a manner that the motion of the disk is made dependent upon the motion of the engine, and that the delivery of lubricating material stops when the engine stops.

AIn the drawing- Y lhe letter A designates an oil-cup, which communicates by means of a channel, a, with the distributing chamber B.

On the upper end of the channel a is formed aseat, b, for a valve, c, which is attached to a screw-spindle, 1, extending up through the top ot' Ythe oil-cup, as shown in'ig. 1.

A nut, e, serves to raise and lower the valve c, and, if .desired, the supply-channel a can be closed by means of 4said valve.

The distributing-chamber B formsthe seat for the distributing-disk G, which is mounted on a stud, f,

and provided with a hub, g, on which swings a lever, D

.This lever carries a click, h, which engages with the yteeth of theratchet-wheel ft, that is firmly secured outhe hub g of the distributing-disk, so that, byirnparting to the lever D 'a vibrating motion, an interxmittent rotary motion is imparted to the disk C.

'It, and gib l.

The gib and key are made topass through a slotted cap, m, which [its over the end of the stud f, and through a slot in saidstud, the cap being made to bear on the end of the hub g'.

The forked end of the gib catches in a neck in the nut k, and, by turning this nut in the proper direction, the key is drawn up andthe disk is forced up against its seat.

Fromthe lower part of the distributing-chamber extends the delivery-channel n through the screwshank- E, which serves to secure the lubricator in the desired position.

In the face of tbe disk is a cavity, o,aud as said disk revolves this cavity sweeps over thek mouth of the supply-channel a, and fills with lubricating material, and, as the motion of the disk progresses, said cavity is made to sweep over the mouth of the delivery-channel n, and the lubricating material contained therein discharges.

lhe quantity of the lubricating material transferred to the delivery-channel for each revolution of the disk .O depends upon the size of the cavity o, and if the motion of the disk is rapid, a larger quantity of lubricating material is transferred to the delivery-chan- V nel than if the motion of the disk is slow.

The lever D is connected to the main ralve-.rod, or to any other moving-part of the engine, so that the speed of the disk is always in proportion to the speed ot" the engine, and the stroke of the lever D may be regulated by increasing or decreasing its length, or in any desirable manner.

When the engine stops, the disk C remains stationary, and no lubricating material is wast-ed.

What I claim as new, and desire to secure by Letters vPatent, is

l. The distributing-diskG, provided with a'cavity, o, in combination with the cup A, distributing-chamber B, and channels a n, substantially as shown and described. y

2. The ratchet-lever D, in combination with the disk O, cup A, distributing-chamber B, and channels a n, substantially as set forth.
